ABSTRACT

A hair care composition having a combination of a mixture of alkyl amine cationic surfactants, high melting point wax to provide a hydrophobic film (frizz resistance) and thermo-pliable film (heat styling response), along with a lightweight conditioner, to produce a hair care composition that is far less susceptible to buildup than traditional products currently marketed.

PRIORITY

This application is a continuation-in-part of U.S. application Ser. No.15/878,890, filed on Jan. 24, 2018, which is herein incorporated byreference in its entirety and claims priority to said application.

FIELD OF THE INVENTION

The present invention provides the qualities expected from a hairconditioner coupled with a unique thermo-pliable film that responds toheat from common consumer hair styling appliances.

BACKGROUND

Consumers desire sufficient detangling, moisturization, and frizzcontrol from hair conditioners that aid in achieving their desiredstyle.

In washing, drying, and styling one's hair several end results aredesired. Firstly, and most obviously, one desires that the hair bethoroughly cleaned. Most desirable is a hair care process whichmaintains the look and feel of clean hair between hair washings. Also inthe cleaning and styling process, one desires hair conditioningproviding ease of combing, relief from static electricity,manageability, and soft hair feel. Generally, these benefits areprovided by a separate hair conditioning product.

Finally, one desires a hair care process or product that provides hairstyling benefits, especially hair style achievement and hold. The desireto have hair retain a particular shape is widely held. Such styleretention is generally accomplished by either of two routes: permanentchemical alteration or temporary alteration of hair style/shape. Atemporary alteration is one which can be removed by water or byshampooing. Temporary style alteration has generally been accomplishedby means of the application of a third separate composition orcompositions to dampened hair after shampooing and/or conditioning. Thematerials used to provide setting benefits have generally been resins orgums and have been applied in the form of mousses, gels, lotions, orsprays. This approach presents several significant drawbacks to theuser. It requires a separate step following shampooing and conditioningto apply the styling composition. In addition, since the style hold isprovided by resin materials which set-up on the hair, the hair tends tofeel sticky or stiff after application and it is difficult to restylethe hair without further application of the styling composition.

Many modern hair styles require the use of heat tools to dry and stylehair to reach a desired look. However, often consumers are frustrated bythe use of such tools as they produce unmanageable hair and increase theoccurrence of undesirable features such as frizz and flyaways.

It has now been discovered that two separate hair care benefits, i.e.,conditioning and styling, can be provided by a single hair care product.In addition, the present invention provides for the ability to use lowtemperature heat of common consumer hair appliances to produce immediatemanageability of hair, wherein the average maximum temperature is lessthan 110° C.

BRIEF SUMMARY

Existing rinse-off products attempt to provide improved styling withconsumer hair appliances through the application of high concentrationof quaternary ammonium cationic surfactant compounds that can build upon hair, leaving it feeling greasy and weighed down. Subsequent uses ofthe conditioner increase static-induced frizz due to the bulky nature ofthe compounds and increased static repulsion between fibers as a result.High viscosity dimethicone/dimethiconols/amodimethicones can also feelgreasy and leave hair feeling weighed down.

Existing leave-on products attempt to provide protection from heat andfrizz through the application of high volatility silicones(phenyltrimethicone/caprylyltrimethicone/cyclohexasiloxane/cyclopentasiloxane) that may provide onlytemporary shine during styling. High viscositydimethicone/dimethiconols/amodimethicones that are used for heatprotection may also leave the hair greasy and weighed down.

This technology relates to a hair care composition comprising a highmelting point waxy material to provide a hydrophobic and thermo-pliablefilm along with a lightweight conditioner, to produce a hair carecomposition that is far less susceptible to buildup than productscurrently marketed. The inclusion of a neutralizing acid, e.g.,glyoxylic acid, acts to control the deposition of the thermos-pliablefilm to minimize unacceptable buildup on hair.

DETAILED DESCRIPTION

The present invention provides the qualities expected from a conditionercoupled with a unique thermo-pliable film that responds to heatgenerated by common consumer hair styling appliances. The compositionmay be applied to wet hair as a rinse off product and/or applied to dampor dry hair as a leave-on product.

This thermo-pliable hair care and styling composition comprises an alkylamine cationic surfactant having a molecular weight from about 400 g/molto about 500 g/mol. The amount of alkyl amine cationic surfactantpresent in the composition may range from about 0.1% to about 7% byweight of, or from about 0.1 to about 5% by weight, or from about 1% toabout 3% by weight, or from about 2% to about 5% by weight. The alkylamine cationic surfactant may be selected from behentrimonium chloride,behenamidopropyl dimethylamine, behentrimonium methosulfate, andmixtures thereof.

The composition may also contain from about 0.1% to 15% long chain fattyalcohols. Examples of such alcohols include behenyl alcohol, cetylalcohol, stearyl alcohol, cetearyl alcohol, arachidyl alcohol, andmixtures thereof. The melting point of long chain fatty alcohol is fromabout 45° C. to about 80° C.

The composition may also contain a high melting point waxy material,having a melting point from about 65° C. to about 90° C., present inamounts ranging from about 0.1% to about 5% (by weight); 1% to about 3%(by weight); or from about 0.75% to about 1.5% (by weight).Specifically, the high melting point waxy material may be selected fromnatural waxes, hydrocarbon waxes, and mixtures thereof, for instance,and not limited to, paraffin wax, ozokerite wax, ceresine wax, carnaubawax, rice bran wax, and mixtures thereof. Also, the composition may alsocontain from about 0.1 to 3% of neutralizing C₂ to C₄ carboxylic acidwith an individual pK_(a) from about 3.1 to about 4.6. Such neutralizingcarboxylic acids may be selected from oxalic acid, glycolic acid, lacticacid, succinic acid, malic acid, and mixtures thereof. A suitable haircare carrier may also be utilized, wherein the point at which thecomposition first begins to melt is less than or equal to any solidmaterials utilized in the composition. The ratio of the cationicsurfactant to the long chain fatty alcohol is from about 1:4 to about1:1.

The onset of melting point (first detectable melting point) for theoverall composition is from about 46° C. to about 90° C.

Generally, for this hair care composition, crystallization point(s) ofthe composition are usually not less than about 46° C.

The hair composition may be in a form chosen from a liquid, a solution,an emulsion, a cream, a gel, a paste, a mousse, a foam, or any otherform that is suitable for application to keratin fibers.
